An acorn, which is the nut of the oak tree, has a hard outer shell that protects its inner seed. This shell can vary in hardness depending on the species of oak, but generally, it's tough enough to withstand environmental conditions and protect the seed from predators. The hardness of an acorn is also essential for its role in germination, as it helps ensure that the seed remains viable until conditions are right for growth. Overall, while not as hard as some other nuts, acorns are relatively tough compared to many seeds.
